Yes, you are permitted to bring standard personal shaving razors on a Royal Caribbean cruise. The cruise line's prohibited items list specifically bans "sharp objects" and "knives," but it makes a clear exception for personal grooming items. This means you can pack disposable razors, cartridge razors (like Gillette or Venus), and electric shavers in either your carry-on or checked luggage. However, there is a strict rule against straight razors (the kind used with an open, exposed blade) and traditional safety razors with loose, double-edged replacement blades, as these are viewed as potential weapons. If you prefer a traditional wet shave, you should stick to the modern cartridge versions while on board. It is also worth noting that while razors are fine, other grooming tools like scissors must have a blade length of less than 4 inches to be permitted. By following these simple guidelines, you can maintain your grooming routine without any issues during the security screening at the cruise terminal.
